Question 10 Which of the following represents a concise, clear statement of the specific goal or aim of a research study? Answer s: a. The purpose of the project was to define changes in blood pressure over time with the four most prevalent treatment modalities prescribed by primary care physicians in the greater Chicago area. b. The phenomenon of depression experienced by school-aged children is an under- researched topic in light of recent research demonstrating the correlation between
childhood obesity and depression. c. Despite the fact that studying the disease, especially from standpoints of prevention and early detection, is costly and time-consuming, it represents a clear priority, since treatment itself is remarkably costly and those affected are not likely to experience even short remissions without early intervention. d. The problem that prompted the study was ignorance surrounding the causation and diagnosis of meningococcal meningitis, especially among soldiers in uniform, and this constituted a significant gap in the literature. Response Feedback : The research purpose is a concise, clear statement of the specific goal or aim of the study that is generated from the research problem. A research problem is an area of concern where there is a gap in the knowledge base needed for nursing practice. Research topics are concepts, phenomena of interest, or broad problem areas that researchers can focus on to enhance evidence- based nursing. One source of research problems is research priorities identified by funding agencies and specialty groups. Question 11
Which of the following study designs focuses on finding a cause and effect relationship among variables, but uses a lower level of control? Answer s: a. Descriptive b. Quasi- experimental c. Phenomenology d. Experimental Response Feedback: Question 12 How does a comparative descriptive design differ from a typical descriptive design? Answer s: a. It differs in name only; they are essentially the same design. b. It examines the relationship between multiple variables, whereas a typical descriptive design only evaluates the effect of one independent variable on one dependent variable. c. It describes data from two different groups, whereas a typical descriptive design focuses on a single group. d. It compares changes in phenomenon over time, whereas the typical descriptive design focuses on only one time period.
Respons e Feedback : The commonly used descriptive study design examines characteristics of a single sample. It identifies a phenomenon of interest and the variables within the phenomenon, develops conceptual and operational definitions of the variables, and describes the variables. The comparative descriptive design examines and describes differences in variables in two or more groups that occur naturally in the setting. Descriptive statistics and inferential statistical analyses may be used to examine differences between or among groups.
